Abstract

The utility model relates to an improved hydraulic lifting conveying cart, which is characterized in that the width and the size of a shovel shelf of loading objects in the vertically forward direction are variable following a width adjusting component of a machine frame mechanism. Consequently, the range of use of the utility model is enlarged. The adoption of an oil pump which can load objects with heavy weight and large sizes and a split driving mechanism of a lifting component leads the utility model to have the advantage of safe operation.

Description

The hydraulic lifting floor truck

The utility model relates to the broad-adjustable hydraulic lifting floor truck of shovel frame that a kind of handling and loading is used, and is particularly useful for the hydraulic lifting floor truck of post and telecommunications internal pair production, processing.

Hydraulic lifting floor truck in the past claims the hydraulic loading-unloading machine again, and as shown in Figure 5 and Figure 6, hydraulic loading-unloading machine 4 is made up of frame mechanism 41, shovel loader structure 42 and driver train 43.The shovel loader structure 42 that adopts chain 421 to be sleeved on lifting roller 434 mainly is made of the shovel frame 420 of metal bracelet 421 and loaded objects, and shovel frame 420 movable sets are connected in the stand of frame mechanism 41 and with chain 421.Driver train 43 is mainly by the oil pump 430 that is loaded on same cylinder body, handle 431, oil cylinder 432, piston 433 and place that the hard lifting roller 434 that connects piston 433 constitutes on the cylinder body.When handle 431 presses oil pump 430 when the high pressure oil mass of oil cylinder 432 is risen, lifting roller 434 is along with piston 433 rises, and chain 421 also drives 420 risings of shovel frame; Otherwise along with oil cylinder 432 oil masses descend, shovel frame 420 falls.The shovel frame width of existing hydraulic loading-unloading machine (vertical loading-unloading vehicle working direction) is that 330mm is non-adjustable, like this vary in size object of size of loading is restricted; Other needs the lifting member of oil lubrication, and promptly chain 421 is used for that post and telecommunications is inner to be prohibited dirt to prohibit production, the disposal field of oil improper.

The purpose of this utility model is to overcome prior art to have weak point, and a kind of adjustable safe and reliable hydraulic lifting floor truck of frame that shovels is provided.

The utility model is realized like this.

Wide and the broadening of the width dimensions of shovel frame on the vertical small car working direction of shovel loader structure of the present utility model along with the accent of frame organization gear tooth bar; The lifting member of lifting shovel frame does not adopt metal bracelet but adopts nonmetallic strap-like member or rope spare; Adopt oil pump and the split type driver train of lifting member can carry big weight object again, safety valve is adopted in the lifting of control shovel frame, control oil mass and reach and limit carrying capacity and adopt check valve, so this driver train operates safe and reliable.

The utility model also has outstanding advantage to be: (1) shovel frame width dimensions is by original fixed value 330mm, and is adjustable wide to 790mm, thereby enlarged the loading scope; (2) promoting the lifting member employing of shoveling frame does not need glossy saddle, has purified the use place.

The utility model is described in further detail below in conjunction with drawings and Examples.
